The 2200 and 2205 are at least 25 years old now. Their caps probably need to be replaced and device technology has moved forward since those days. Just due to these two points, the newer Mcs will sound better (i.e. more transparent). I used to have a 2125 and it didn't sound nearly as good as my 7200. I am not yet convinced that autoformers are the end all but the 402 sounds absolutely incredible.
